St. Mary's College, Sault Ste. Marie, Ontario

St. Mary's College is a high school in Sault Ste. Marie, Ontario, Canada. It was established in 1956 by Basilian priests as an all-boys Catholic high school on St. Georges Avenue. As the school grew in popularity and size, St. Mary's began admitting girls in September 1987. That same year, the school moved into a new building (the former location of Lakeway Collegiate & Vocational School or Sault Technical and Commercial High School) built in 1921 on Wellington Street. In 2015, St. Mary's College combined with St. Basil Secondary School in a brand new building located on Second Line East.
